13.1 Auto Setting
Automatic settings will choose appropriate time base scales, amplitude scales and triggering parameters according to the
input signal so that the waveform automatically properly displays on the screen. Press the AUTO key to enable automatic
settings.
Automatic setting applies only to the following conditions:
①
Automatic setting is suitable for setting up simple single frequency signals, and not for complex combination waves.
②
The measured signal frequency is not less than 20Hz, the amplitude is not less than 20mVpp, and the square wave duty
cycle is more than 5%.
③
The automatic setting is only for the open channels and not for the closed channels.
13.2 Run / Stop
Use the RUN/STOP key on the front panel for control. When the key is pressed and the green light is on, it indicates the
RUN state, and if the red light is on after the key press, it is the STOP state. In the running state, the oscilloscope is
continuously acquiring waveforms and the upper part of the screen shows “AUTO”; in the stop state, the oscilloscope
stops the acquisition and the upper part of the screen shows “STOP”. Press the RUN/STOP key to switch the waveform
sampling between the run and stop states.
13.3 Clear
Press the CLEAR button on the front panel of the oscilloscope to clear the loaded REF waveform on the screen.
13.4 Factory Setting
By pressing the DEFAULT button, you can quickly restore to factory settings. UPO2000E series oscilloscope factory
